Specification forming part of Letters Patent no. 159,222, dated January 26, 1875; application and August 11, 1874.

To all whom it may-concern:

Be it known that I, CHARLES J, Sums, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Dredging-Bucket; and that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawings and to the letters of reference marked thereon, making a part of this specification.-

This invention is in the nature of an improvement in dredgingbuckets; and. the invention consists of a dredging-bucket constructed in four sections, each of said sections f being supported and braced by means hereinafter specifically described, and opened and closed by separate chains.

In excavating still clays and hard sand it is sometimes found ditficult to get the bucket to enter 'suilieiently to scrape up the load. To insure this under almost all circumstances is the principal feature of my invention, as will be-seen from the following description and accompanying drawings, wherein Figure 1 is an end view of my improved bucket, and Fig. 2 a plan view of same.

Similar letters of reference indicate like parts in the several figures.

A represents the sections of my bucket. These sections may be-sections'of a sphere, spheroid. or sections of any desirable geometrical figure. Fixed to the lower ends of the guide-poles B is a cross-bar, G, and to this cross-bar, at right angles to the same, and midway between the guide-poles, is a second cross-bar, D. Secured to and extending from one cross-bar to the other are brace-barsa, to

which are secured blocks b. these blocks are curved and grooved at their ends, and are attached to the brace-bars a near their 'outer ends. .Firmly fixed to the upper and inners'iirl'ace of each of the, sections A are tie-rods c. These tie-rods extend to each side of the blocks b, and in this way the several sections are secured to the blocks and the rest of the supporting trams-work. Secured to each of the sections A is a chain, 0, uniting with a drawchain, E, and secured to the under side of the blocks b are the ends of chainsf, which unite in a common draw-chain, F. I

My buck t being constructed substantially as above described, its operation" is, as follows The draw-chain E beingdrawn up by any suitable power, the several-- sections open outward, the blocks b turning on the brace-bars a for that purpose, and the section's being in this way opened, the bucket is lowered to the surface itis intended to excavate, when the.

raw-chainE is slackened and the chain F is drawn up, which causes the blocks b (which act as levers) to turn on the brace-bars a and draw the several sections A together simultaneously, and as they are thus drawn together their sharplower points enter into and their.

angular edges cut the clay, &c.,' scraping together, so that as the sections close in it is gathered up into the sections, which, when finally closed together, retain "it until it is drawn upward, when the chain F is slackened .and the draw-chain E dawu up, causing the herehr described, constructed with cross-bars C and D, combined with brace-bars a, blocksb, and tie-rods c, as shown. tor the purpose or sustaining the sections.
